FOUNTAIN-FEED DRAWING- PEN v Application filed October 15, 1928. SerialNo. 312,413.

attachment of the barrel, or handle of the pen and the nib membersthereof; 7

These and other objects and features of the invention will be fullydescribed in the following specification and claims and illustrated inthe accompanying drawings, in which: s Fig. 1 shows a side view of thepen. 'Fig. 2 shows a front View of same.

Fig. 3 shows, on an enlarged scale, a section on the line 3-3 of figure1.

Fig. 4 shows, also enlarged,.a'section on the line 44 of" figure 3.

' Fig. 5 shows a plan view of the valve seat removed from the casing.

Referring first to figures 1 and 2 of the drawings; the principleelements of thepen are as follows: 8 v The valve sleeve 10, the barrellland the nibs 12. The barrel has a screw cap 13 for filling and the nibshave the usual thumb adjusting screw 14. In operation; ink is releasedonto the distributor blade 15 by pressing on the button 16 the action ofwhich will be described later.

Now, referring to figures 3, 4 and 5 of the drawings; it will be seenthat the valve seat 17 is screwed into the sleeve 10 coming to rest atthe point 18. It has a boss on its lower face which fits into a recessin the rotatable valve disk 19, the said recess being indicated by thedotted line 20. a

The disk 19 is securedby the bolt 21 whichv has a nut 22 thereon and ascrew head 23 v at its lower extremity. A spring 2 1.1naintains asuitable pressure on the valve disk. An elongated hole, or duct 25passes through the valve seat and permits the ink to flow from thereservoir 26 when the hole 27 of the j valve disk is in open alignment;j- Y Secured to the disk 19 in the manner illustrated in figure 4, isthe push-rod 28 which, beingheld by the screw pin 29 passes through theslot indicated by the dotted lines 30 and through the spring clip 31terminating in the button 16. A supplementary spring 32 augments theaction ofthis rod. I When thecducts are closed, as is the case when therod is fully out; the hole' 27 rests 0 ata pointin advance of the hole25.

The elongated shape of the hole 25 as seen in fig ure 5, permits of aflow of ink for a longer period when the button is pressedthan would bethe case if it were simply round as the 05- h0le-27. The holes 33indicated in the valve seat pass only partly through the same and arefor aid in assembling; a spanner being used for the purpose.

Thenibs 12 are secured to the plug 34 together with the distributorblade 15. This plug is screwed into the sleeve 10 and leaves clearanceforthe rotating of the valve disk 19.

While the device is shown and described in its preferred form; it isunderstood that such minor changes may be made therein as may comewithin the spirit and scope of the appended claims. 1

Having thus described my invention, what Iclaim as new and desire tosecure by Letters 30 Patent, is as follows: I

A reservoir valve comprising a seat within a sleeve and the said seathaving a downwardly disposed boss thereon, a rotatable disk recessed tofitover the said boss and s5 secured in position thereon 'by means of acentral bolt and a tension spring which bears against the bolt head andthe base of the said disk, an elongated-holein the seat element and aperforation in the rotatable disk so which is adapted to be brought intoalignment with the said elongated hole when actuated by a push rod whichis pivotally attached to the said disk at an 011' center point of sameand which rod is retractable by means of a spring located between theouter wall of the said sleeve and a button head on the said push rod.
